9.4 Fresh water system maintenance
9.4.1 Fresh water tank
The fresh water tank is placed at stern and can be inspected through the
helm gear compartment.
Clean the tank inside at least once a year.
Pump check and cleaning
− Check the cleanliness of the pump and of the captive air tank. Wash
them with well-diluted detergent, and then dry them.
− Check the fittings for tightness and evidence of corrosion.
− Check the air pressure inside the tank. If it is lower, restore it to a
maximum with a bicycle pump or a compressor. For range values
refer to the specific equipment manufacturer’s handbook.
9.4.2 Water system maintenance
For service purposes, you may isolate parts of the system or individual
services without affecting the general system operation. To do this,
handle on suitable valves installed on the main manifold. Also, to stop a
failure in the hot water system, you can close the valves located at the
water heater inlet. Check and clean the fresh water tank at least every
three months. Fill the tank with clean water, and then drain it. Repeat the
operation two to three times. You may add an appropriate disinfectant or
a sanitizing product through the tank fill fitting. Follow the directions on
the product label. Fill and drain the tank at least one more time, after
draining the water containing disinfectant or sanitizing agent. Verify for
possible leaks in the system at least once every six months. Verify the
operation of the cocks at least once a month.
NOTICES
Before servicing the fresh water tank, disable the operation of the fresh
water system.
